Installing pip is a simple 2-step operation.

first, you have to get the latest version of pip installer file.

second, You have to run a SELECT duns, confidencecode, deliveryaddressseq, customercode, [rank] FROM (SELECT *, RANK() OVER (PARTITION BY duns ORDER BY confidencecode DESC, deliveryaddressseq, customercode) AS [rank] FROM t_duns) tt WHERE [rank] = 1 on the file you have downloaded.

the file you download in the first step is named duns confidencecode deliveryaddressseq customercode rank 1001 10 1 501 1 1002 10 0 504 1 1003 10 0 507 1 and, when ran using python is going to download and install pip on your os.

and you can always read the documentations.
